9. On behalf of IWG SLR, the expert from IEC introduced a draft Resolution on the common specification of light source categories (ECE/TRANS/WP.29/GRE/2015/28 and GRE-74-06), proposals for simplifying Regulations Nos. 37, 99 and 128 by moving data sheets for various light sources from these Regulations to the Resolution as well as some further modifications (ECE/TRANS/WP.29/GRE/2015/25, ECE/TRANS/WP.29/GRE/ 2015/26, ECE/TRANS/WP.29/GRE/2015/27, GRE-74-03, GRE-74-04, GRE-74-05, GRE-74-17, GRE-74-18 and GRE-74-24). The experts from Germany, France, Italy, Netherlands and EC delivered a number of remarks on these proposals, mainly of a terminology nature. The expert from France also requested that all modifications to Regulations Nos. 37, 99 and 128 be clearly explained in the “Justification” section of the respective documents.

10. GRE stressed the need to ensure the high quality of these documents before submitting them to WP.29 and requested IWG SLR to update the proposals based on the comments received and to submit a revised package for consideration at the next session. Some experts pointed out that the guidance by OLA on establishing a new HRD Resolution (see para. 7 above) was also applicable to the draft Resolution on light sources. GRE recalled that this approach had already been endorsed by WP.29 at its November 2014 session. Nevertheless, GRE requested its Chair to ask WP.29, at its forthcoming session in November 2015, to reconfirm this mandate in the light of the OLA guidance.

7. GRE took note of the progress of the Informal Working Group “Simplification of the Lighting and Light-Signalling Regulations” (IWG SLR) and of its forthcoming meetings. The secretariat informed GRE about the guidance provided by the United Nations Office for Legal Affairs (OLA) and WP.29 on different options for the so-called Horizontal Reference Document (HRD) (ECE/TRANS/WP.29/1116, WP.29-166-18 and GRE-74-15). In particular, OLA had pointed out that using a new part B of Regulation No. 48 as HRD would contradict the terms of the 1958 Agreement. With regard to establishing a new Resolution, OLA had indicated that Regulations can only be amended in accordance with the procedure set out in Article 12 of the Agreement and that a Resolution cannot be employed to amend a Regulation. OLA had also proposed, as an alternative solution, to amend the 1958 Agreement with a specific procedure applicable in those cases when an amendment to one Regulation would affect the application of other Regulations.

8. The expert from EC was of the view that the alternative solution proposed by OLA would bring no results, in view of its complexity and the advanced stage of work on Revision 3 of the 1958 Agreement. He also expressed concerns about the regulatory status of a new Resolution outside the legal text of the 1958 Agreement. The expert from UK shared these concerns. Various experts raised questions on using dynamic or static references to HRD in the individual device Regulations. GRE noted that dynamic references could provide more benefits in terms of simplifying the text, but some Contracting Parties might prefer static references for legal reasons. GRE also wondered about the correlation between amendments to HRD and supplements or new series of amendments to individual device Regulations, including transitional provisions. GRE requested IWG SLR to address the identified issues and to report to the next session on its findings.

On behalf of the Informal Working Group “Simplification of the Lighting and Light-Signalling Regulations” (IWG SLR), the expert from IEC introduced a revised proposal for the draft Resolution on the common specification of light source categories (ECE/TRANS/WP.29/GRE/2016/5 and Corr.1, GRE-75-02, GRE-75-03 and GRE-75-04), together with proposals for simplifying Regulations Nos. 37, 99 and 128 by moving light sources data sheets from Annex 1 to these Regulations to the Resolution (ECE/TRANS/WP.29/GRE/2016/2, ECE/TRANS/WP.29/GRE/2016/3 and ECE/TRANS/WP.29/GRE/2016/4). The experts from Germany, France, Italy, UK, CLEPA, GTB and OICA commented on the proposals, in particular on phasing out of light source categories and on the legal form of amendments to Regulations Nos. 37, 99 and 128 (supplements or new series of amendments).

8. GRE adopted the draft Resolution on the common specification of light source categories (ECE/TRANS/WP.29/GRE/2016/5 and Corr.1), as amended by Annex II, and requested the secretariat to submit it to WP.29 for consideration at its November 2016 session. GRE also adopted proposals for amendments to Regulations Nos. 37, 99 and 128 (ECE/TRANS/WP.29/GRE/2016/2, ECE/TRANS/WP.29/GRE/2016/3 and ECE/TRANS/WP.29/GRE/2016/4) not amended and requested the secretariat to submit them to WP.29 and the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their November 2016 sessions as, respectively, draft Supplement 45 to the 03 series of amendments to Regulation No. 37, draft Supplement 12 to the original version of Regulation No. 99 and draft Supplement 6 to the original version of Regulation No. 128.

99. The secretariat informed the World Forum about the proposal for a draft Consolidated Resolution on the common specification of light source categories (ECE/TRANS/WP.29/2016/111). The World Forum adopted the draft Consolidated Resolution with the assigned number R.E.5. WP.29 noted that this Resolution should enter into force on the same date as Supplement 45 to the 03 series of amendments to Regulation No. 37 (Filament lamps), Supplement 12 to the original version of Regulation No. 99 (Gas-discharge light sources) and Supplement 6 to the original version of Regulation No. 128 (Light Emitting Diode (LED) light sources) (agenda items 4.6.1, 4.6.11 and 4.6.12 above).

OLA had also proposed, as an alternative solution, to amend the 1958 Agreement with a specific procedure applicable in those cases when an amendment to one Regulation would affect the application of other Regulations.

8. The expert from EC was of the view that the alternative solution proposed by OLA would bring no results, in view of its complexity and the advanced stage of work on Revision 3 of the 1958 Agreement. He also expressed concerns about the regulatory status of a new Resolution outside the legal text of the 1958 Agreement. The expert from UK shared these concerns. Various experts raised questions on using dynamic or static references to HRD in the individual device Regulations. GRE noted that dynamic references could provide more benefits in terms of simplifying the text, but some Contracting Parties might prefer static references for legal reasons. GRE also wondered about the correlation between amendments to HRD and supplements or new series of amendments to individual device Regulations, including transitional provisions. GRE requested IWG SLR to address the identified issues and to report to the next session on its findings.
